5、People diet to look more attractive．Fish diet to avoid being beaten up，thrown out of their social group，and getting eaten as a result．That is the fascinating conclusion of the latest research into fish behavior by a team of Australian scientists．

The research team have discovered that subordinate fish voluntarily diet to avoid challenging their larger competitors．“In studying gobies we noticed that only the largest two individuals，a male and female，had breeding（繁殖）rights within the group，” explains Marian Wong．“All other group members are nonbreeding females，each being 5-10% smaller than its next largest competitor．We wanted to find out how they maintain this precise size separation．”

The reason for the size difference was easy to see．Once a subordinate fish grows to within 5-10% of the size of its larger competitor，it causes a fight which usually ends in the smaller goby being driven away from the group．More often than not，the evicted fish is then eaten up．

It appeared that the smaller fish were keeping themselves small in order to avoid challenging the boss fish．Whether they did so voluntarily，by restraining how much they ate，was not clear．The research team decided to do an experiment．They tried to fatten up some of the subordinate gobies to see what happened．To their surprise，the gobies simply refused the extra food they were offered，clearly preferring to remain small and avoid fights，over having a feast．

The discovery challenges the traditional scientific view of how boss individuals keep their position in a group．Previously it was thought that large individuals simply used their weight and size to threaten their subordinates and take more of the food for themselves，so keeping their competitors small．

While the habits of gobies may seem a little mysterious，Dr．Wong explains that understanding the relationships between boss and subordinate animals is important to understanding how hierarchical（等級的）societies remain stable．

The research has proved the fact that voluntary dieting is a habit far from exclusive to humans．“As yet，we lack a complete understanding of how widespread the voluntary reduction of food intake is in nature，” the researchers comment．“Data on human dieting suggests that，while humans generally diet to improve health or increase attractiveness，rarely does it improve long-term health and males regularly prefer females that are fatter than the females’ own ideal．”

4、Andrew Ritchie，inventor of the Brompton folding bicycle，once said that the perfect portable bike would be “l(fā)ike a magic carpet…You could fold it up and put it into your pocket or handbag”．Then he paused： “But you'll always be limited by the size of the wheels．And so far no one has invented a folding wheel．”

It was a rare — indeed unique — occasion when I was able to put Ritchie right．A 19th-century inventor，William Henry James Grout，did in fact design a folding wheel．His bike，predictably named the Grout Portable，had a frame that split into two and a larger wheel that could be separated into four pieces．All the bits fitted into Grout's Wonderful Bag，a leather case．

Grout’s aim：to solve the problems of carrying a bike on a train．Now doesn’t that sound familiar? Grout intended to find a way of making a bike small enough for train travel：his bike was a huge beast．And importantly，the design of early bicycles gave him an advantage：in Grout’s day，tyres were solid，which made the business of splitting a wheel into four separate parts relatively simple．You couldn't do the same with a wheel fitted with a one-piece inflated（充氣的） tyre．

So，in a 21st-century context，is the idea of the folding wheel dead? It is not．A British design engineer，Duncan Fitzsimons，has developed a wheel that can be squashed into something like a slender ellipse（橢圓）．Throughout，the tyre remains inflated．

Will the young Fitzsimons's folding wheel make it into production? I haven't the foggiest idea．But his inventiveness shows two things．First，people have been saying for more than a century that bike design has reached its limit，except for gradual advances．It's as silly a concept now as it was 100 years ago：there's plenty still to go for．Second，it is in the field of folding bikes that we are seeing the most interesting inventions．You can buy a folding bike for less than ?1，000 that can be knocked down so small that it can be carried on a plane — minus wheels，of course — as hand baggage．

Folding wheels would make all manner of things possible．Have we yet got the magic carpet of Andrew Ritchie’s imagination? No．But it's progress．

1．We can infer from Paragraph 1 that the Brompton folding bike _________．

A．was portable                                              B．had a folding wheel

C．could be put in a pocket                              D．looked like a magic carpet

2．We can learn from the text that the wheels of the Grout Portable _________．

A．were difficult to separate                             B．could be split into 6 pieces

3．We can learn from the text that Fitzsimons's invention _________．

A．kept the tyre as a whole piece                      B．was made into production soon

C．left little room for improvement                    D．changed our views on bag design

4．Which of the following would be the best title for the text?

A．Three folding bike inventors                         B．The making of a folding bike

C．Progress in folding bike design                     D．Ways of separating a bike wheel
